摘要:

为探索宝兴县硗碛火腿的风味形成机制,以火腿发酵第1、45、90、135、180、225 天的股二头肌为研究对象,采用以75μm CAR/PDMS 为萃取纤维头的固相微萃取法结合气质联用仪对硗碛火腿发酵过程中挥发性风味成分的变化进行分析。结果表明:硗碛火腿的挥发性风味成分总计71 种,包括醛、醇、酸、烃、酮、酯、酚类及其他化合物类;相对含量最高的风味成分为醛类;在火腿的整个发酵过程中,酸类、醛类、烃类、类、酚类和其他化合物类的相对含量总体呈上升趋势,醇类、酮类的相对含量逐渐下降。醛、醇、酸、烃、酮、酯、酚类等化合物的共同作用形成了硗碛火腿独特的风味特征。

Abstract:

In order to explore the mechanism of flavor formation in Qiaoqi ham, biceps femoris from ham fermented 1, 45, 90,135, 180 days and 225 days was used as the experimental subject to analyze volatile flavor compounds by gas chromatographymassspectrometry and solid phase micro-extraction with 75μm CAR/PDMS as the fiber probe. Results indicated that 71 volatile flavor compounds including aldehydes, alcohols, acids, hydroearbons, ketones, esters and phenols were identified in Qiaoqi ham. Aldehydes exhibited the highest content in all volatile flavor compounds. During the fermentation processing, the relative contents of acids, aldehydes, hydroearbons, esters and phenols exhibited an increased trend, whereas alcohols and ketones exhibited a decreased trend. The characteristic flavor of Qiaoqi ham is engendered by the integration of aldehydes, alcohols, acids, hydroearbons, ketones, esters, phenols and other compounds.

Key words: Qiaoqi ham, volatile flavor compounds, solid phase micro-extraction, gas chromatography and mass pectrometry(GC-MS)
